AIPAC-aligned PACs pour $25.6 million into Kentucky primary targeting Rep. Massie

Ad spending in the Kentucky 4th District Republican primary between Rep. Thomas Massie and Trump-backed challenger Ed Gallrein reached $25.6 million by early May 2026, making it the most expensive House primary in U.S. history. AIPAC's United Democracy Project spent $2.6 million, the Republican Jewish Coalition spent $4 million, and the MAGA KY super PAC spent $5.6 million opposing Massie. Billionaire Paul Singer funded both MAGA KY and AIPAC-aligned groups.
